Is simple, you follow people on Twitter. If you go to a persons web page and look up their followers (or people who follow them) and you find people you would like to chat with, see their cool updates etc. you click the follow button. And most of the time people follow you back, this is how you become popular on Twitter. You post updates, you chat with everyone, talk about personal experiences or post stuff you found on the news. It's really all about you and your connection with friends. I'll look you up and I'll follow you (follow me too okay?)
